Welcome to the Fitbit Community, @Nicolerenaeton.

Thanks for the details shared in your post. I appreciate your efforts and recommend trying the following:

1. Force close the Fitbit app and then, on your phone, go to Settings > Bluetooth and turn Bluetooth off and back on after 10 seconds.

2. Perform a restart on device: How do I restart my Fitbit device?

3. Restart your mobile device. 

You can confirm the steps to connect your card in What should I know about Fitbit Pay? 

Hope this helps.
